Yep..lean is V-Bad.
I read somewhere and I am not quoting the source...but something about running duel fuel filters, one at the pump and one at the engne solved a guys richness problem (black smoke and smell at 2KRPM) on a BMW M5.
I wonder if this is viable at all and would help?
The car will only usually take in only the amount of fuel it needs...but also some of the bimmer guys are posers making $hit up on the fly...so I have no idea if this is even do-able to solve anything.
Just knowledge (good or bad) exchange.
